To all whom it may concern:

Be it known that I, GUSTAV BLASS, manufacturer, subject of the German Emperor, residin at Rotthausenerstrasse, Caternberg, hineland, .Germany, have invented newand useful Improvements in Processes for Solidifyin Fats, Oils, Tar, Resin which the follhwing is a specification. I Naphthalene hashitherto been added to oils in order tothereby obtain a lubricant of increased consistency. By such a 'process,

however, partly by reason of the low melting point of na hthalene (80 C.) it isnot ossible to obtain ubricants which are s ciently solid during use,,for instance, with heavy and easily heatmg bearings, and furthen such lubricants in conse uence of the comparativel great hardness of t e na hthalene do not lubrl eate cold bearings an tory as lubricants. In the first case, that is to say with all journals which tend to become heated, the naphthalene as carrier of the lubricant has also the drawback that it decreases the total lubricating action, because it. has, even in a fluid condition, only very moderate lubricating properties and t us so to speak has a diluting action on the actual lubricant. It also happens that naphthalene evaporates even at a ow temperature and then gives ofi an annoym may be annoying and unwholesome for work- L men employed m a trade. All these drawbacks are removed if crude anthracene, (also solid lubricants, and these substances be added to the lubricant in such proportionate equivalents, that the solid constituents serve as carriers for the lubricant The anthracene shall be used in the state after ressing out thesoft particles or in the pur' ed condition, the impurities (.parafiin and the like) having been removed 'by'meansgof a-convenient solvent.

Instead of lubricants, "other: sofflsubstances, such-as tar, pitch or the like may also be converted into solid bodies by the same process.

By the .use of crude anthracene and -the like as carrier for the fluid, semi-fluid,

substances in question, since the melting; I

kind that, for instance, lubricants obtained by the present process retain their form and are consumed extremel economically even in the case of heavy an easily heating bearings. The lubrication is also a thoroughly practical one, as, on the onehand the anthracene itself acts as a lubricant, and on the other hand on account of the anthracene remaining solid, no evaporation of the lubricant itself takes place.

By reason of its solid formjthe lubricant may be employed-on beari shafts or" the like without a ubricator, an on the rotation of the said arts,,-the giving off of deleterious.

and unwho esom odors-is entirely avoided.

This improved process may be carried out practically in various ways. Anthracene is preferably minted with oil, fat, tar resin,

wax,- pitch, asphalt, soap and the 'ke, or

mixtures of the same, the com ound is melted and then allowed to cool, idesired under agitation. On' cooling a crystallization of the anthracene. takes lace, and these innumerable small c stas form a skeleton in the interstices of w ioh the introdu'cedsubstances are'deposited.

If substances the melting point of which lies below thatv of anthracene are to be brought into asolid form or mademore solid in condition the process may also be carried out in the following way:The anthracene is first melted separately, run into molds and then allowed to cool. Crystallization of the mass then again takes place, innumerable intercommum'catin spaces being formed between the crystals. is then immersed in the oil, grease or the like which has been reduced to a fluid condition, or the latter is poured over it until the desired quantity is absorbed in the mass.

One example of each of the methods here- 'in'before described of carryin out the prochlS crystalline mass ess will now be more particular y described:

Example 1. 50 parts of anthracene 30 parts of wool grease acid or sebacic acid 20 parts of oil of any suitable origin are melted together and then 4 parts of powdered lime added under vigorous agitation. When saonification has taken place the .mass is adled out and allowed to rapidly cool. Example 2. The mass formed of anthracene by melting and molding is placed in castor oil until 10 of the latter is absorbed.

Substances which are tliemselves'of a consistent nature obtain a more solid form by 0., solid bodies are obtained of such a 1 treatment according to the foregoing proorial. It is of importance that the substances in question should not lose their particular techmcally valuable properties bythe treat- -rnent hereinbeforedescribed as'no solution .m xa. chenucal sense-fisformed by melting the and substances with anthraceue, but only a fluid mixture isobtained which on coohnfi' yields a --thorough. mixture of the' origins. substances, the solid constituentsof .the anthraeene crystallizing out.
